Triumph Trident T150

The Ogle styling made the T150’s looks unpopular at launch in 1968, especially in the hugely important USA market where they longed for a faster Bonneville look-alike. The problem was resolved by supplying US dealers with the so called “beauty kit” that made the bike much more recognisable as a Triumph. Styling aside, its breathtaking performance and taut handling drew many admirers. A road test by Motor Cycle News timed the bike at 130mph on a one-way run. Prophetically, the rider said that the triple’s distinctive exhaust note would go down in history. Today, classic owners look upon the “breadbin” tank and raygun silencers with much more affection and so the T150 has become a very popular machine.
